Getting the Code Examples Working

The most common reason for being unable to get a code example to work (assuming

you haven’t made any typos) is a failure to set up the Flash file according to the

instructions. Reread the surrounding text and follow the steps carefully. Be sure to

place the code where it belongs (usually in the first frame of a layer named Scripts or

Actions or in an external .as or .asc file). When compiling AS 2.0 code, be sure you’ve

set the compiler version to ActionScript 2.0 under File

➝ Publish Settings ➝ Flash ➝

ActionScript Version.

Any code example that accesses movie clips, buttons, or text fields via ActionScript

won’t work unless you set the item’s instance name properly. To set the instance

name for a movie clip, button, or text field, select it on stage and enter the instance

name on the left side of the Properties panel (Window

➝ Properties) where you see

the placeholder “<Instance Name>”.

Another common source of problems is failure to set a symbol’s linkage identifier

properly, as is necessary when accessing Library symbols from ActionScript. To set

the linkage identifier for a symbol, check the Export for ActionScript and Export in

First Frame checkboxes in the Symbol Properties or Linkage Properties dialog box.

(These are accessible by selecting a symbol in the Library (Window

➝ Library) and

choosing either Properties or Linkage from the Library panel’s pop-up Options

menu.) Then enter the identifier in the field labeled Identifier (which isn’t active until

Export for ActionScript is checked).

Read the instructions carefully to make sure you haven’t confused a movie clip

instance name with a symbol linkage identifier.

If you still can’t get it working, download the examples from the book’s web site,

contact O’Reilly book support, or check the book’s errata page. If all else fails, get a

tutorial book on Flash or ask an experienced Flasher for help.
